Template extension aliasing, use .markdown for markdown files

[zachleat]

Some mechanism to allow extension of existing template engines with additional file extensions.

@paulrobertlloyd surfaced this in #117 (comment) with the desire to use .markdown.

I wonder if it would be useful to remove the original .md if you’re using something else or if supplementing is sufficient.

Also a request in #223 to use .mst as a mustache alias via @coolshaurya

[coolshaurya]

The default file extension used for template engines should be the most commonly used extension - .md for markdown , .hbs for handlebars , .mst for mustache ,.html for HTML etc. which mostly happens to be the shortest extension among the 2 file extensions that some template engines have.

[zachleat]

Just a cursory look at the mustache.js docs would suggest .mustache is more commonly used than .mst but we’ll probably support both moving forward (after this feature is included)

cc @medfreeman can you upvote here instead of #124? Thanks!

Please see the limitation of the current implementation at #207 and let me know what you think. Wondering how deep to go here.

[zachleat]

As it stands, this is slated for 0.7.0.

[zachleat]

Sorry but this is being punted out of 0.7.0 for now. I’m not happy with my implementation and I think it will cause headaches so I will revisit for a future release!

[zachleat]

Keep in mind the relevant (closed) discussion at #319. We’ll coalesce here at this issue.

I would love to add aliases for existing formats. We have a custom markdown file format called mathpix markdown which is supported through markdown-it plugin but the extension is .mmd. We want to support both .md and .mmd with eleventy.

I think there was some progress on this at #319, I really don't think anyone wants to not use the default and only pick up the added aliases.

Aliasing would be great. Don’t need replacement.

I’m pro .markdown (as is its creator).
